Out with the old, in with the new

Justin, the $2K is a good chunk of change for sure. The 727 is capable. Resell the 727 & roll it over into the 904.
The 904 is just simply a lighter (lbs.) weight trans that uses less power to drive the wheels. The mandatory converter change and what ever else that needs to be, can add up. But for racing, it’s what you would rather have. But not must have unless, IMO, your racing for the money.

I have a good 727, steel front drum, billet servo's and accumulator, good steels and clutches, some oiling mods and the governor removed. I'm into the converter a ton, almost $1200 new, it was built for my 408 (never worked well) and was sent back when the 434 ( didn't work for it either, 17% slip) was built and dynoed, almost $300 more + shipping. It still didn't work so it was sent to another converter guy, another $175 + shipping and it works pretty good now.
A local guy has some 904's but getting him to move is almost impossible.

Local guy whittled on them one evening( very sharp guy) best 350 i have ever spent( he literally spent one evening on them)
He didnt flow them, but the car went 12 teens its first outing with untouched eddies. After his portwork, a swap from a Mopar single plane to an air gap, cam change and the previously mentioned milling..... the car went from 12.17 at 109 to 11.26 at 118.40. Milling raised the compression up around 10.4 . Those were the only changes.

27 in the hole slugs, 28 gasket, 58 cc head
Before i swap in the stroker, i might just put my 904 and yet to be bought new 904 convertor behind this mill. I was convinced i could get this thing to run 10's by doing that. Would like to prove it before moving on to the stroker.

Nice guy , for his work.... Talk about bang ,for the buck...
